The invention discloses a device for measuring an antenna standing wave ratio. The device is characterized by comprising two identical power threshold detection devices. The first power threshold detection device (10) is used for detecting the power P1 of a first transmitting signal (01); the second power threshold detection device (20) is used for detecting the power P2 of a second transmitting signal (02); the distance L1=lambda / 2 between the first power threshold detection device (10) and an antenna (40) is set, the distance L2=lambda / 4 between the second power threshold detection device (20) and the antenna (40) is set, and lambda is the transmitting signal wavelength P2; and the power P1 of the first transmitting signal 01 and the power P2 of the second transmitting signal 02 are used for calculating the antenna standing wave ratio. The problem that the existing antenna standing wave ratio measurement system is low in processing precision is solved.
Description
technical field [0001] The invention relates to a detection method of a wireless communication device, in particular to a device and a method for standing wave ratio of an antenna. Background technique [0002] Mobile communication is an indispensable means of civil communication. It enables people to exchange information anytime, anywhere, in a timely and reliable manner, without limitation of time and space. Its flexible and maneuverable characteristics meet the needs of rapid changes in the battlefield situation and frequent movement of troops in modern warfare. , so it also plays an important role in military communications. As the throat of the wireless communication system, the antenna plays a very important role in the overall performance of the mobile communication system. Antennas and feeders often work abnormally due to unexpected events. Whether they can be monitored in real time and report fault alarm signals is an urgent problem to be solved. [0003] The trad...
